I think you should reinstall with the latest version. The result is normal when I check it. ` import vnquant.DataLoader as dl

loader = dl.DataLoader('VND', '2018-02-02','2018-04-02', data_source='VND', minimal=True)

data = loader.download()

print(data.head()) `

Result:

`2021-05-11 15:40:20,743 : INFO : data VND from 2018-02-02 to 2018-04-02 have already cloned!
